• Abstract:

  In order to solve the problem that the real label representation effect of the remote practical teaching interactive system is not significant and affects the accuracy of data response, a remote practical teaching interactive system based on immersive VR is designed. In the hardware part, multiple ADC are used for synchronous acquisition and processing, and LUDS synchronous clock chip is used to transmit the synchronous clock between multiple boards. The software part designs the overall framework of system development. In the VR development module, a practical teaching reality label enhancement model is established based on immersive VR to identify objects and realize immersive stereo display. In the human-computer interaction module, the interaction mode of remote practical teaching is designed to update the visual scene and provide information feedback to users. The black box test of the system shows that the measured results are consistent with the expected results, and the response data accuracy of the system is 97.76%, which is 4.51% and 5.12% higher than those based on cloud technology and data mining, respectively, and can improve the interactive performance.
